RAID Levels Explained:
- RAID 0 (dividendo en franxas): Combines drives for maximum speed and capacity, but offers no data redundancy.
- RAID 1 (Replicación): Duplicates data across drives for redundancy, sacrificing half the total capacity for data protection.
- SPAN (Concatenation): Combines drives into a single large volume without striping or mirroring.
- JBOD (Só un feixe de discos): Treats each drive as an independent volume.
